In an effort to reduce traffic, New York launched a program that charges a toll to enter defined areas that are often congested. To see if the program works, Joshua Moshes and Benjamin Moshes, as a student project, made a tracker that logs Google Maps traffic data at checkpoints. Current travel times are compared against average times before the program launch.
It looks like there’s a shift on this first day, and I am sure many other cities are watching.
